Limits of Transmit and Receive Array Gain in Massive MIMO
Tobias Laas, Josef A. Nossek, Wen Xu
In this paper, we consider the transmit and receive antenna array gain of massive MIMO systems. In particular, we look at their dependence on the number of antennas in the array, a…

On Reciprocity in Physically Consistent TDD Systems with Coupled Antennas
Tobias Laas, Josef A. Nossek, Samer Bazzi +1
We consider the reciprocity of the information-theoretic channel of Time Division Duplex (TDD) Multi-User-Multiple Input Multiple Output (MU-MIMO) systems in the up- and downlink.…
